CVE-2025-23006 is a critical pre-authentication deserialization of untrusted data vulnerability in SonicWall Secure Mobile Access (SMA) 1000 Series appliances, specifically in the Appliance Management Console (AMC) and Central Management Console (CMC). Under specific conditions, the vulnerable management components deserialize attacker-controlled data before authentication, which can allow a remote unauthenticated attacker to trigger arbitrary operating system command execution on the appliance. The issue affects vulnerable SMA1000 builds up to and including 12.4.3-02804, and has been reported as exploited in the wild, including as a zero-day. The weakness is classified as CWE-502.

Repository purpose: a Python-based SonicWall “Security Audit Toolkit” plus a Docker CTF-style lab that simulates and (in solutions) exploits two critical SonicWall CVEs. Top-level structure: - sonicwall_audit.py: main orchestrator CLI that runs modules (ssl, cve, auth, web) against a target https://<host>:<port>, writes JSON/text reports to reports/. - validate_cves.py: standalone deep validators for CVE-2021-20038 and CVE-2024-53704 using non-destructive behavioral checks. - modules/: implementation of auditors/validators and report generation. - lab/: docker-compose lab with two containers: - cve-2021-20038: Apache + deliberately vulnerable 32-bit CGI binary /usr/lib/cgi-bin/sslvpnclient (and symlinks portal/welcome/etc). Protections disabled (no canary, execstack, no PIE, ASLR disabled in entrypoint) to make stack overflow exploitation feasible. - cve-2024-53704: Flask/Gunicorn SSLVPN simulator on 4433 with vulnerable swap cookie deserialization (conditional HMAC verification). - lab/exploits/: skeleton exploit templates (incomplete). - lab/solutions/: working exploits. Exploit capabilities present: 1) CVE-2024-53704 (auth bypass via cookie forgery): Working exploit forges a base64-encoded JSON session cookie named swap with {username, authenticated:true} and omits sig_version so the server skips HMAC verification. It then accesses /virtual-office/ and /dashboard to retrieve the flag. 2) CVE-2021-20038 (stack buffer overflow -> RCE): Working exploit crafts a URL-encoded query string payload to overflow a 4096-byte stack buffer in the CGI handler (strcpy of QUERY_STRING). Payload includes a NOP sled, null-free 32-bit x86 Linux shellcode that runs /bin//sh -c "cat /root/flag.txt", padding to offset 4100, and an attacker-chosen return address into the sled. Output is returned in the HTTP response body. Important distinction: the main toolkit modules and CVE validators are primarily scanners/validators and explicitly avoid destructive exploitation; the actual exploitation code is confined to the lab solution scripts intended for the local practice environment.
